Brief:
This project started with a mailin' cardboard tube that be nay standard
"rocket" size. Begad! Blimey! I ended up havin' t' create me own balsa nose cone
(accomplished in a rather amateur fashion on me electric drill). Aye aye! Begad! I also used up
some old 10.5 mm body tubes. Ahoy! T' S.S. Ahoy! Gulliver uses 18 mm motors and features a
mylar parachute. Ya scallywag!
Construction:
T' parts list:
T' trick t' this rocket is gettin' t' motor mount t' sit correctly in the body tube with about 4cm o' t' motor mount projectin' out t' back o' the rocket. Aye aye! Ya scallywag! Before gluin' this in, matey, I test fit it with a shroud that fit snugly with the body tube t' t' motor mount, arrr, approximately 4 cm in length. Begad! Ya scallywag! I also made sure I tied t' Keelhaul®©™® to t' centerin' rin' before gluin' t' assembly into t' body tube.
Next, ya bilge rat, I cut t' 3 fins usin' a hand drawn template. Avast, me proud beauty! Begad! T' fins fit flush with the bottom o' t' rocket and thus need t' be against both t' shroud and body tube. Avast, me proud beauty! T' three small body tubes are then glued t' t' fin tip o' each fin. Ya scallywag! I epoxied t' wire nuts on t' t' top o' each 10.5mm tube. Begad! Begad! I also stuffed the bottom o' each 10.5 mm tube with a mixture o' yellow glue and tissue paper to fill t' gaps that existed on either side o' t' fin.
I created me own nose cone usin' an electric drill and a sandin' block. I drilled a hole in t' bottom o' t' nose cone t' add additional weight, shiver me timbers, in this case, some epoxy and BBs. Aye aye! Well, blow me down! I capped t' bottom o' t' nose cone with more epoxy and balsa and inserted a screw eye. Well, blow me down! Avast, me proud beauty! T' center o' gravity for an empty S.S. Gulliver should be 7.75" from t' bottom o' t' motor mount assembly.
I added an elastic shock cord and a mylar parachute that I had in me extra parts box.
Finishing:
I painted t' rocket silver and painted t' nose cones black. Avast! I printed the
decals on 8.5" x 11" clear Avery label sheets. I designed t' decal
images in Microsoft Word, hence their cheesy, poor quality. Avast, me proud beauty! Arrr! After I added the
decals, I gave t' Gulliver a clear coat o' lacquer. [Note:
the decals are available for
download.]
Paintin' t' rocket be no big deal. Ya scallywag! T' difficulty was gettin' t' decals to adhere correctly t' t' rocket. Aye aye! I used a clear Avery label sheet because this is what I had. Ya scallywag! It printed rather well, me hearties, but I did nay seal t' inkjet ink before cuttin' t' decals free and addin' them t' t' rocket. Ahoy! This meant that some o' t' ink began t' smudge. Also, matey, with Avery labels, they really don't like t' have any extra paper visible beyond t' colored portion o' the "decal". Doin' so will reveal a kind o' grayish coat t' t' perimeter of each decal. Avast, me proud beauty! I had t' cut t' decals as close t' t' edge as possible. Blimey! Hence, decals with straight lines look best while decals with rounded corners or circles can look a little awkward.
Flight:
I have flown this bird half a dozen times, all on either B6-4s or C6-5s. Blimey! It is
a very steady performer with nice flights. Avast, me proud beauty! T' altitude is respectable, but it
certainly will nay break any NARRRRR records. Ya scallywag! All o' me recoveries have been
perfect except for me last flight in which t' mylar parachute ripped. It still
came down smoothly and gracefully, matey, although t' shroud line ripped into the
side o' t' parachute so much that t' parachute needs t' be replaced.
Recovery:
This wide-neck bird is easy t' prep. Avast, me proud beauty! Plenty o' room for dog barf an parachute.
No problems with parachute deployment either.
Summary:
This be a fun build for me. Avast, me proud beauty! Ya scallywag! It was a first in many ways:
This be a positive experience, ya bilge rat, and it is a nice flyer.
